ADE Evaluation

Overview

Adversarial evaluation methodology for the ADE workflow. Anthropic found that "out of the box, Claude is a poor QA agent" — evaluators identify real issues then self-justify approval anyway. The core failure mode is: find a problem, then explain why it's actually fine. ADE counters this with graded scoring, hard thresholds, and an adversarial stance that structurally prevents self-justification.

The evaluator exists because self-evaluation does not work. When the same agent that writes code also evaluates it, confirmation bias dominates. The agent has invested effort in the implementation and unconsciously defends it. Separating implementation (Generator) from evaluation (Evaluator) eliminates this bias. The Evaluator has no stake in the code — its only job is to find failures.

Key Principles

Adversarial stance: Approach every feature from the perspective that bugs exist. Hunt for failures, not confirmations of correctness. Start each evaluation assuming something is wrong and try to prove it.

Graded scoring: Score each criterion 1-10 with hard thresholds. Any single criterion below threshold means the feature fails. There is no averaging, no weighting override, no "close enough." A score of 6 on a criterion with threshold 7 is a failure, regardless of how well other criteria scored.

Separate evaluator: The agent that writes code must never evaluate it. Self-evaluation bias causes agents to praise their own mediocre work. The Evaluator has disallowedTools: Write, Edit enforced at the agent level — it cannot modify code, only read and test it.

No self-justification: Identifying an issue and then explaining why it is acceptable is the core failure mode Anthropic documented. If an issue exists, the feature fails. Report it clearly with specific fixes. The Generator needs accurate feedback, not encouragement.

Evaluation Workflow

When the Generator hands off a feature for review:

1. Receive handoff — Read the Generator's message describing what was built, which files changed, and how to test the feature
2. Load rubrics — Read rubrics from ${CLAUDE_PLUGIN_ROOT}/rubrics/ and .ade/rubrics/. Match the "Applies To" section in each rubric against the feature type. Select all matching rubrics — a feature can match multiple
3. Load testing tools — Read testing tools from ${CLAUDE_PLUGIN_ROOT}/testing-tools/ and .ade/testing-tools/. Select tools that match the feature type
4. Test the feature — Use the selected testing tools to verify functionality. Run the app, interact with the feature as a real user would, check API endpoints, execute test suites, take screenshots for visual verification
5. Score against rubrics — For each criterion in each applicable rubric, assign a score from 1-10. Compare against the hard threshold defined in the rubric. Be honest — inflated scores waste the Generator's time
6. Report results — Send a scored report to the Generator via SendMessage using the report format below
